It's a triangle, right?
Solve for 'x' and find out where the distribution ends.
All else should be relatively clear from there.
Note: Are you serious about "c"? That can't be typed correctly.
A density curve consists of a straight line segment that begins at the origin (0,0) and has a slop 1.
b) determine the median, first quartile, and third
c) relative to the median, where would you expect the mean of the distribution?
d) what percent of the observations lie below .5? above 1.5?
I have the answers but i do not know how to get them. Can someone show me how there problems work?
